摘要
针对含多端SNOP的柔性互联配电网无功优化问题,提出一种兼顾有功网损最小和电压偏差最小的优化模型。对于目标函数的不同约束条件,利用多目标遗传算法对目标函数进行求解寻优。在改进的IEEE 14节点系统中,对所提出的运行优化模型进行验证和分析。仿真结果表明,智能软开关的引入可以有效提升柔性互联配电网性能,减少电压波动,提高电网的稳定运行水平与能量传输能力。
In view of the reactive power optimization of flexible interconnected distribution network with multi-terminal SNOP,an optimization model with minimum active power loss and minimum voltage deviation is proposed.The multi-objective GA(genetic algorithm)is used to optimize the objective function according to its different constraints.The proposed operation optimization model was validated and analyzed in the improved IEEE 14 node system.The simulation results show that the introduction of SNOP can effectively improve the performance of flexible interconnected distribution network,reduce voltage fluctuation,and improve the stable operation level and energy transmission capacity of the power network.
